The invention relates to a brake pedal push rod stroke amount correction method, which comprises the following steps: when a vehicle satisfies a brake pedal push rod stroke amount correction condition, calculating the deviation between a push rod stroke actual measurement and a push rod stroke calculation amount, the push rod stroke actual measurement being a quantity measured by a brake pedal push rod stroke sensor of the vehicle, and the push rod stroke calculation amount being a quantity measured by a brake pedal push rod stroke sensor of the vehicle; the push rod stroke calculation amount is the amount calculated according to the brake master cylinder pressure of the vehicle and a preset mapping relation; and compensating and correcting the quantity measured by the brake pedal push rod stroke sensor according to the deviation to obtain the brake pedal push rod stroke correction quantity. The invention further provides a device, a vehicle and a storage medium. According to the brake pedal push rod stroke amount correction method, the stroke amount measured by the brake pedal push rod stroke sensor can be corrected, so that the influence of external factors on the stroke amount measured by the brake pedal push rod stroke sensor is corrected, and then the consistency of the braking requirement calculated by the vehicle DBR function and the braking requirement of a driver is ensured.
本发明涉及一种制动踏板推杆行程量修正方法,包括以下步骤:当车辆满足制动踏板推杆行程量修正条件时,计算推杆行程实测量和推杆行程计算量的偏差,推杆行程实测量是由车辆的制动踏板推杆行程传感器所测得的量,推杆行程计算量是依据车辆的制动主缸压力,按照预设映射关系所算出的量;依据偏差对制动踏板推杆行程传感器所测得的量进行补偿修正,得到制动踏板推杆行程修正量。本发明还提出了一种装置、车辆及存储介质。本发明提出的制动踏板推杆行程量修正方法能够修正制动踏板推杆行程传感器所测得的行程量,以修正外界因素对制动踏板推杆行程传感器所测得的行程量的影响,进而确保车辆DBR功能算得的制动需求与驾驶员的制动需求的一致性。
